Title: Organometallic polymers
IPC: C08G79/14
Filed: 1957-12-24
Abstract: Polymers are prepared having the formula <FORM:0880910/IV (a)/1> wherein A and C are organic radicals, and B and D each represent an organic radical, an oxygen atom, or another polymeric unit; M and M1 represent dissimilar metallic elements selected from metals of the Group III, IV, V, VI and VII-A, the metalloids, boron, silicon, arsenic and tellurium, and phosphorus, at least one of said dissimilar metallic elements being capable of producing a polyhydroxide which releases a proton in the presence of a strong base; L and L1 each represent an oxygen or sulphur atom, a carbon-containing linking group or a divalent = NR group wherein R is a hydrogen atom or an organic radical; c and d are integers and a and b are zero or integer; x and y are integers and Z is an integer greater than one.  The preparation consists in condensing (a) an appropriate organic metallic-element-containing compound wherein the metallic element is M as defined above and is attached directly to B (if organic) and to A, via a carbon atom thereof with (b) an appropriate organic metallic-element-containing compound wherein the metallic element is M1 as defined above and is attached directly to D (if organic) and to C, via a carbon atom thereof.  In general x and y are 1-200 and Z is 2-2000.  The substituents B and D (when organic) and the substituents A and C may be acyclic or carbocyclic groups or heterocyclic groups having oxygen, sulphur or nitrogen, as the hetero atom.  The linking groups L and L1, when organic, may be aliphatic or aromatic and may be attached to the metallic elements M and M1 via carbon, oxygen, sulphur or nitrogen atom; further the groups L and L1 may be substituted by halogen, oxygen, sulphur, nitro or amino groups and may be interrupted by oxygen, sulphur or nitrogen atoms, e.g. in furan, thiophene, pyrrole, pyrazole, oxazole, isothiazole, oxathiazole, pyrazine or indole rings.  In some of the processes for making the polymers, catalysts may be used, e.g. acids or bases, Lewis acids, or free radical initiators; some of the processes are catalyzed by radiation.  Some of the polymers are soluble in hydrocarbons, higher ethers, cyclic ethers, and polyethers (e.g. dioxane) and polyethers of polyhydric alcohols. They are useful as damping fluids, hydraulic fluids, heat-transfer media, lubricant additives or in the manufacture of surface coatings or moulded articles.  In examples, (1) Diphenyl silane diol was reacted with diphenyl tin oxide to produce <FORM:0880910/IV (a)/2> Instead of a silane diol the diols of titanium, molybdenum, manganese, aluminium, boron or arsenic may be used; (2) Diphenyl tin dimethoxide was reacted with diphenyldichlorosilane to give <FORM:0880910/IV (a)/3> Instead of the diphenyl tin dimethoxide, the corresponding dimethyl, dibutyl, dicyclohexyl or methyl phenyl tin dimethoxides may be used. Similarly, diphenyl tin dimethoxide may be reacted with methyl aluminium sesquichloride, diethyl germanium dibromide, ethyl boron trichloride or ethyl bismuth diiodide; (3) The sodium derivative of diphenyl silane diol was reacted with diphenyl tin dichloride to produce <FORM:0880910/IV (a)/4> (4) Dimethyltin dichloride was reacted with p-phenoxyphenyl-p-t-butylphenyl silanediol to produce <FORM:0880910/IV (a)/5> (5) Isopropyl-2-naphthyl tin dichloride was reacted with diphenyldichlorosilane to produce <FORM:0880910/IV (a)/6> (6) Methylphosphoric acid was reacted with dimethyltin oxide to produce <FORM:0880910/IV (a)/7> (7) Phenylphosphoric acid was reacted with methylaluminium dimethoxide to produce <FORM:0880910/IV (a)/8> (8) Diphenyltin dichloride was reacted with diphenyl silane dithiol to produce <FORM:0880910/IV (a)/9> (9) Octamethylcyclotetrasilazane was reacted with dimethyltin amide to produce <FORM:0880910/IV (a)/100> (10) Diphenylsilane dial was reacted with dimethyl manganic hydroxide to produce <FORM:0880910/IV (a)/111> (11) Dimethoxydiphenyl silane was reacted with dibutyl tin dimethoxide to produce <FORM:0880910/IV (a)/122> (12) Diamino phenylsilane was reacted with diphenytindimethoxide to produce <FORM:0880910/IV (a)/133> (13) Diphenyl tin dihydroxide was reacted with diphenylsilanediol to produce <FORM:0880910/IV (a)/144> (14) Phenylarsonic acid was reacted with dimethyltin oxide to produce <FORM:0880910/IV (a)/155> (15) Octamethylcyclotetrasiloxane was reacted with dimethyl tin oxide to produce <FORM:0880910/IV (a)/166> (16) Methylarsine was reacted with dimethyldivinyl tin to produce <FORM:0880910/IV (a)/177> Similarly the divinyl compounds of manganese, aluminium, boron, arsenic or gemarnium may be reacted with dimethyl stannane or diphenyl stannane; (17) Ethylaluminium dihydride was reacted with divinyl diphenyl tin to produce <FORM:0880910/IV (a)/188> In a similar process, there may be used phenylboron dihydride, phenylphosphine or diphenyl divinylsilane; (18) Phenyl boron dihydride was reacted with divinyl dimethyl germanium to produce <FORM:0880910/IV (a)/199> Phenylphosphine was reacted with diethyl diallyl tin to produce <FORM:0880910/IV (a)/200> (20) Diphenyldivinylsilane was reacted with methylphosphine to produce <FORM:0880910/IV (a)/211>
